DETAILED DESCRIPTION OF EMBODIMENTS OF THE PRESENT INVENTION

Embodiments of the present invention are described in detail with reference to the accompanying drawings.

In the following description, the same or similar reference numerals may be used for the same or similar elements when they are illustrated in different drawings. Detailed descriptions of constructions or processes known in the art may be omitted to avoid obscuring the subject matter of the present invention.

FIG. 1 is a detailed block diagram of a mobile device 100 according to an embodiment of the present invention.

Referring to FIG. 1, the mobile device 100 may include a display unit 110, a storage unit 120, a pressure detecting unit 130, a manipulating unit (or user interface unit) 140, and a control unit 150.

The display unit 110 displays images corresponding to various functions of the mobile device 100, which include images corresponding to currently-executed applications and Graphic User Interfaces (GUI) for manipulation by the user.

The storage unit 120 stores programs that execute various functions of the mobile device 100, including application programs. The storage unit 120 may be implemented as a hard disc, nonvolatile memory, etc.

The pressure detecting unit 130 detects pressure exerted on a specific area of the mobile device 100. More specifically, the pressure detecting unit 130 detects whether pressure is applied to the pressure detecting unit 130 and a magnitude of the applied pressure. The pressure detecting unit 130 may be implemented as a variety of pressure detecting sensors, including, for example, a piezo sensor.

A piezo sensor does not require a separate power supply at an atmospheric condition. As pressure is applied, the piezo sensor generates electric power and perceives the applied pressure according to the voltage of the electric power as generated. Accordingly, by maintaining the piezo sensor in an activated state when the mobile device 100 is at an atmospheric condition, standby power can be minimized and power consumption can be reduced.

The manipulation unit (or user interface unit) 140 receives various manipulations from a user, and transmits the input user manipulations to the control unit 150. The manipulation unit (or user interface unit) 140 includes a variety of user interface devices. More specifically, the manipulation unit (or user interface unit) 140 may include a proximity sensor unit 142, a touch detecting unit 144 and a button unit 146.

The proximity sensor unit 142 detects whether a user, for example, is located at a predetermined proximity of the proximity sensor unit 142. The proximity sensory unit 142 may also detect a gesture at a predetermined proximity of the proximity sensor 142. The term “proximate gesture” herein refers to a gesture made by the user with a body part (such as hand, for example) placed at a proximity to the proximity sensor unit 142. For example, the proximate gesture may include a user's hand moving in a specific direction at a proximity to the proximity sensor unit 142.

The proximity sensor unit 142 includes at least one Light Emitting Diode (LED). A proximity sensor unit 142 including only one LED may detect whether an object is at a proximity to the proximity sensor unit 142, while a proximity sensor unit 142 including two LEDs may additionally detect the proximate gesture and proximity coordinates. A proximity sensor unit 142 with several LEDs may be able to detect the proximate gesture with increased accuracy compared to a proximity sensor unit having only two LEDs.

The touch detecting unit 144 detects touch manipulation by the user. The touch detecting unit 144 may be implemented as a touch screen.

The button unit 146 detects a button manipulation by the user. The button unit 146 includes at least one button. For example, the button unit 146 may include a number button, a direction button, etc.

The control unit 150 controls the overall operation of the mobile device 100, according to a user manipulation input through the manipulation unit (or user interface unit) 140. The control unit 150 controls so that the manipulation unit (or user interface unit) 140 is activated upon detection of applied pressure by the pressure detecting unit 130. Specifically, the control unit 150 controls the mobile device 100 so that, upon detection of the applied pressure at the pressure detecting unit 130, at least one of the proximity sensor units 142, the touch detecting unit 144 and the button unit 146 is activated. The term “activated” herein, with reference to the proximity sensor unit 142, refers to a state in which the proximity sensor unit 142 is able to detect whether an object is at a proximity and whether a proximate gesture is performed at the proximity. The term “activated” herein, with reference to the touch detecting unit 144, refers to a state in which the touch detecting unit 144 is able to detect the presence of touch manipulation. The term “activated” herein, with reference to the button unit 146, refers to a state in which the button unit 146 able to detect the presence of button manipulation.

Specifically, if the pressure detecting unit 130 detects applied pressure and the proximity sensor unit 142 detects a proximate gesture while a specific application is being executed, the control unit 150 performs functions related to the specific application and the detected proximate gesture. Furthermore, if the pressure detecting unit 130 detects the applied pressure and the touch detecting unit 144 detects presence of a touch manipulation while a specific application is being executed, the manipulation unit 130 performs functions related to the specific application and the detected touch manipulation. If the pressure detecting unit 130 detects applied pressure and the button unit 146 detects the presence of button manipulation while a specific application is being executed, the manipulation unit 130 performs functions related to the specific application and the detected button manipulation.

The control unit 150 may additionally determine a function to perform in response to the manipulation input through the manipulation unit (or user interface unit) 140, according to the magnitude of the detected pressure.

If the pressure detecting unit 130 includes one or more pressure detecting areas, the control unit 150 may additionally determine a function to perform in response to the manipulation input through the manipulation unit (or user interface unit) 140, according to the specific pressure detecting area of the pressure detecting areas that detects the pressure.

The control unit 150 may additionally determine a function to perform in response to the manipulation input through the manipulation unit (or user interface unit) 140, according to a number of times the pressure is detected at the pressure detecting unit 130.

The control unit 150 may also control the mobile device 100, such that the methods or processes for providing UI are provided as explained below with reference to FIGS. 2 to 20C.

FIG. 2 illustrates the pressure detecting unit 130, the proximity sensor unit 142, the touch detecting unit 144 and the button unit 146 arranged on an outer portion of the mobile device 100, according to an embodiment of the present invention.

Referring to FIG. 2, the mobile device 100 includes the pressure detecting unit 130 on both side portions thereof. The mobile device 100 also includes the touch detecting unit 144 on a display screen to provide a touch screen function. Additionally, the mobile device 100 includes the proximity sensor unit 142 and the button unit 146 on a lower portion of the screen.

The arrangement of components illustrated in FIG. 2 is provided only as an example. The pressure detecting unit 130, the proximity sensor unit 142, the touch detecting unit 144 and the button unit 146 of the mobile device 100 may be provided in different arrangements according to embodiments of the present invention.

User manipulation on the mobile device 100 is explained in detail below with reference to FIGS. 3A to 3C.

FIG. 3A illustrates a user manipulation method using the pressure detecting unit 130 and the proximity sensor unit 142, according to an embodiment of the present invention.

Referring to FIG. 3A, as a user holds the mobile device 100 on both side portions thereof, the mobile device 100 detects applied pressure through the pressure detecting unit 130 arranged on both side portions. Accordingly, if the pressure detecting unit 130 detects the applied pressure, the mobile device 100 activates the proximity sensor unit 142 so that the proximity sensor unit 142 detects whether the user is at a proximity to the proximity sensory unit 142 and also detects whether a proximate gesture is performed.

Since the proximity sensor unit 142 is activated in response to the detection of the applied pressure at the pressure detecting unit 130, the proximity sensor unit 142 only detects gestures that are intentionally input by the user. Furthermore, since the proximity sensor unit 142 is in a deactivated state in a standby mode when the pressure detecting unit 130 does not detect any pressure, the mobile device 100 uses only a minimum level of electricity in the standby mode.

FIG. 3B illustrates a user's manipulation method using the pressure detecting unit 130 and the touch detecting unit 144 of the mobile device 100, according to an embodiment of the present invention.

As explained above with reference to FIG. 3A, the mobile device 100 detects the applied pressure through the pressure detecting unit 130 arranged on both side portions, as the user holds the mobile device 100 on both sides. Accordingly, as the pressure detecting unit 130 detects the applied pressure, the mobile device 100 activates the touch detecting unit 144 so that the touch detecting unit 144 perceives the touch manipulation by the user on the display screen.

Since the touch detecting unit 144 is activated in response to the detection of the applied pressure at the pressure detecting unit 130, the touch detecting unit 144 only detects touches that are intentionally input by the user. Furthermore, since the touch detecting unit 144 is in a deactivated state in a standby mode where the pressure detecting unit 130 does not detect the pressure, the mobile device 100 needs a minimum level of electricity in the standby mode.

FIG. 3C illustrates a user manipulation method using the pressure detecting unit 130 and the button unit 146, according to an embodiment of the present invention.

Referring to FIG. 3C, as the user holds the mobile device 100 on both side portions thereof, the mobile device 100 detects applied pressure through the pressure detecting unit 130 arranged on both side portions. Accordingly, if the pressure detecting unit 130 detects the applied pressure, the mobile device 100 activates the button unit 146 so that the button unit 146 perceives whether the user is at a proximity, and also perceives whether a proximate gesture is performed.

Since the button unit 146 is activated in response to the detection of the applied pressure at the pressure detecting unit 130, the button unit 146 only detects gestures that the user intends to input. Furthermore, since the button unit 146 is in a deactivated state in a standby mode where the pressure detecting unit 130 does not detect the pressure, the mobile device 100 only requires a minimum level of electricity in the standby mode.

As explained above, the proximity sensor unit 142, the touch detecting unit 144 and the button unit 146 of the mobile device 100 are in a deactivated state if the pressure detecting unit 130 does not detect the applied pressure. Then, in response to the detection of pressure at the pressure detecting unit 130, at least one of the proximity sensor unit 142, the touch detecting unit 144, and the button unit 146 is changed to an activated state.

Accordingly, the mobile device 100 requires only a minimum level of power consumption in a standby mode. A user is also able to input an intended manipulation without error, since the can input an intention to provide input manipulation through the pressure detecting unit 130.

FIG. 4 is a flowchart illustrating a method of the mobile device 100 for providing a UI, according to an embodiment of the present invention.

At step S405, the mobile device 100 keeps the manipulation unit (or user interface unit) 140 in a deactivated state. At step S410, the mobile device 100 determines whether the pressure detecting unit 130 detects pressure. At S410-Y, if the pressure detecting unit 130 detects applied pressure, the mobile device 100 activates the manipulation unit (or user interface unit) 140, at step S420.

At step S430, the mobile device 100 determines whether a proximate gesture is detected at the proximity sensor unit 142. At step S430-Y, if the proximity sensor unit 142 detects proximate gesture, at step S435, the mobile device 100 performs a function corresponding to the proximate gesture detected at the proximity sensor unit 142.

At step S440, the mobile device 100 determines whether a user's touch manipulation is detected at the touch detecting unit 144. At step S440-Y, if the touch detecting unit 144 detects the user's touch manipulation, at step S445, the mobile device 100 performs the function corresponding to the touch manipulation detected at the touch detecting unit 144.

At step S450, the mobile device 100 determines whether the button unit 146 detects a user's button manipulation. At step S450-Y, if the button unit 146 detects the user's button manipulation, at step S455, the mobile device 100 performs the function corresponding to the button manipulation detected at the button unit 146.

Accordingly, the mobile device 100 is capable of providing a UI, using the pressure detecting unit 130 and the manipulation unit (or user interface unit) 140. According to the above-described method for providing a UI according to an embodiment of the present invention, since the button unit 146 is activated in response to the detection of applied pressure at the pressure detecting unit 130, the button unit 146 detects only the gesture intended by the user. Furthermore, since the button unit 146 is in a deactivated state in a standby mode where pressure is not detected by the pressure detecting unit 130, the mobile device 100 requires only a minimum level of electricity in the standby mode.

As explained above, the proximity sensor unit 142, the touch detecting unit 144 and the button unit 146 are in a deactivated state unless the pressure detecting unit 130 detects pressure. Accordingly, in response to the detection of pressure at the pressure detecting unit 130, at least one of the proximity sensor unit 142, the touch detecting unit 144, and the button unit 146 is changed to an activated state.

Accordingly, the mobile device 100 consumes a minimum level of electricity in a standby mode. Additionally, the user is able to input an intended manipulation without errors, since the user can input an intention to start inputting manipulations through the pressure detecting unit 130.

Manipulation of the mobile device 100 is explained in greater detail below, with reference to related drawings. FIGS. 5A to 5C illustrate a process of changing the mobile device 100 from hold-on state to hold-off state, according to an embodiment of the present invention.

FIG. 5A illustrates a lock screen 500 displayed on a screen of the mobile device 100 according to an embodiment of the present invention. Referring to FIG. 5A, the pressure detecting unit 130 is arranged on both side portions of the mobile device 100, and the proximity sensor unit 142 is arranged on a lower portion of the screen. As the user holds the mobile device 100 with fingers contacting the pressure detecting unit 130, the proximity sensor unit 142 is activated from a deactivated state.

FIG. 5B illustrates a user inputting a proximate gesture to the proximity sensor unit 142 from the right to the left according to an embodiment of the present invention. As illustrated in FIG. 5B, in response to the user's proximate gesture input in a leftward direction to the proximity sensor unit 142 in a state that the user is holding the pressure detecting unit 130, the mobile device 100 performs an unlocking function.

Accordingly, as illustrated in FIG. 5C, the mobile device 100 is changed to unlocked state and displays the unlocked screen 510 on the screen.

As explained above, the mobile device 100 is capable of unlocking according to a manipulation input to the pressure detecting unit 130 and the proximity sensor unit 142.

FIGS. 6A to 6C illustrate a process of changing the mobile device 100 from a hold-off state to hold-on state, according to an embodiment of the present invention.

FIG. 6A illustrates the unlocked screen 600 appearing on the screen of the mobile device 100 according to an embodiment of the present invention. Referring to FIG. 6A, the pressure detecting unit 130 is arranged on both side portions of the mobile device 100, and the proximity sensor unit 142 is arranged on a lower portion of the screen. As the user presses the pressure detecting unit 130 twice as shown in FIG. 5A, the proximity sensor unit 142 is activated from a deactivated state, and a screen 610 to set a lock appears as illustrated in FIG. 6B. A ‘screen 610 to set lock’ is a transition screen provided to indicate a transition from an unlocked state to a locked state according to an input of a specific manipulation.

FIG. 6B illustrates a user inputting a proximate gesture to the proximity sensor unit 142 in a leftward direction, to initiate a lock function according to an embodiment of the present invention.

Referring to FIG. 6B, as the user presses the pressure detecting unit 130 twice and inputs a proximate gesture to the proximity sensor unit 142 in a leftward direction, the mobile device 100 performs the lock function in response.

Accordingly, as illustrated in FIG. 6C, the mobile device 100 changes to the locked state and the locked state 620 is displayed on the screen.

As explained above, the mobile device 100 is capable of performing a lock function according to a manipulation input to the pressure detecting unit 130 and the proximity sensor unit 142.

Meanwhile, the mobile device 100 may perform different functions in response to the same manipulation, depending on the respective pressure detecting areas of the pressure detecting unit 100. This performance of different functions is explained in greater detail below with reference to FIGS. 7A to 8B.

FIGS. 7A and 7B illustrate a mobile device 100 performing different functions for respective pressure detecting areas of the pressure detecting unit 130, according to an embodiment of the present invention.

The pressure detecting unit 130 includes a first pressure detecting area 130 a and a second pressure detecting area 130 b. Referring to FIG. 7A, the first pressure detecting area 130 a corresponds to an upper area on a left side of the mobile device 100, and the second pressure detecting area 130 b corresponds to a lower area on the left side of the mobile device 100.

FIG. 7A illustrates an example in which the first pressure detecting area 130 a of the mobile device 100 detects the applied pressure, and the user's proximate gesture is input in leftward direction to the proximity sensor unit 142. Referring to FIG. 7A, if a user's proximate gesture is input into the proximity sensor unit 142 in leftward direction while user is pressing on the first pressure detecting area 130 a of the pressure detecting unit 130, the mobile device 100 performs a corresponding application (i.e., application A) in response.

FIG. 7B illustrates another example in which the second pressure detecting area 130 b of the mobile device 100 detects applied pressure, and the user's proximate gesture is input, to the proximity sensor unit 142, in a leftward direction. Referring to FIG. 7B, if a user's proximate gesture is input into the proximity sensor unit 142 in the leftward direction while the user is pressing the second pressure detecting area 130 b of the pressure detecting unit 130, the mobile device 100 performs a corresponding application (i.e., application B) in response.

As explained above, the pressure detecting unit 130 may include multiple pressure detecting areas, and the mobile device 100 may perform different functions in response to the same proximate gesture manipulation, depending on the areas that detect the pressure.

FIGS. 8A and 8B illustrate the mobile device 100 performing different functions for respective pressure detecting areas of the pressure detecting unit 130, according to an embodiment of the present invention.

The pressure detecting unit 130 includes a first pressure detecting area 130 a and a second pressure detecting area 130 b. Referring to FIG. 8A, the first pressure detecting area 130 a corresponds to an upper area on a left side of the mobile device 100, and the second pressure detecting area 130 b corresponds to a lower area on the left side of the mobile device 100.

FIG. 8A illustrates an example in which the first pressure detecting area 130 a of the mobile device 100 detects applied pressure, and the user inputs manipulation through a specific button 146 of the mobile device 100. Referring to FIG. 8A, if a user inputs manipulation through the specific button 146 while pressing the first pressure detecting area 130 a of the pressure detecting unit 130, the mobile device 100 performs a corresponding application (i.e., application A) in response.

FIG. 8B illustrates another example in which the second pressure detecting area 130 b of the mobile device 100 detects an applied pressure, and the user inputs a manipulation through the specific button 146 a of the mobile device 100. Referring to FIG. 8B, if a user inputs manipulation through the specific button 146 a while pressing the second pressure detecting area 130 b of the pressure detecting unit 130, the mobile device 100 performs a corresponding application (i.e., application B) in response.

As explained above, the pressure detecting unit 130 may include multiple pressure detecting areas, and the mobile device 100 may perform different functions in response to the same button manipulation, depending on the areas that detect the pressure.

Accordingly, the mobile device 100 may perform different functions in response to the same touch manipulation, depending on areas that detect the pressure.

Meanwhile, the mobile device 100 may provide different functions in response to the same manipulation, depending on the magnitude of pressure detected as the pressure detecting unit 130. Referring to FIGS. 9 to 11E, a process of providing different functions in response to the same manipulation, depending on the magnitude of pressure detected as the pressure detecting unit 130, is explained below in greater detail.

FIG. 9 is a table of the UI functions according to the magnitude of pressure detected at the pressure detecting unit, and the proximate gestures detected at the proximity sensor unit 142, according to an embodiment of the present invention.

Referring to FIG. 9, according to an embodiment of the present invention, the magnitude of pressure may include three stages, such as “weak”, “intermediate,” and “strong.” The proximate gestures may include two categories according to distance, such as, a “near” proximate gesture and a “far” proximate gesture. The “near” proximate gesture refers to an instance where the user's hand is very close to the proximity sensor unit 142, and the “far” proximate gesture refers to an instance where the user's hand is relatively further away from the proximity sensor unit 142.

If the pressure detecting unit 130 detects “weak” pressure, and the proximity sensor unit 142 detects the “near” proximate gesture, photographs are turned slowly as a corresponding UI function. If the pressure detecting unit 130 detects “weak” pressure, and the proximity sensor unit 142 detects the “far” proximate gesture, photographs are turned quickly as a corresponding UI function. If the pressure detecting unit 130 detects “intermediate” pressure, and the proximity sensor unit 142 detects the “near” proximate gesture, several photographs are turned at once the corresponding UI function. If the pressure detecting unit 130 detects “strong” pressure, and the proximity sensor unit 142 detects the “near” proximate gesture, several photographs are turned quickly as the corresponding UI function.

FIGS. 10A to 10C illustrate a process of providing user input such that a next photograph is displayed on the screen, according to an embodiment of the present invention. FIG. 10A illustrates an example in which the pressure detecting unit 130 detects applied pressure, and the user's proximate gesture is input in a leftward direction into the proximity sensor unit 142. Referring to FIG. 10A, if the user inputs a proximate gesture in the leftward direction into the proximity sensor unit 142, while applying pressure on the pressure detecting unit 130, the mobile device 100 performs the page-turning function as a corresponding function.

FIG. 10B illustrates an example in which the pressure detecting unit 130 detects applied pressure, and the user's touch manipulation is input, into the proximity sensor unit 142, in a leftward direction. Referring to FIG. 10B, if the user inputs touch manipulation in the leftward direction into the proximity sensor unit 142, while applying pressure on the pressure detecting unit 130, the mobile device 100 performs the page-turning function as a corresponding function.

FIG. 10C illustrates an example in which the pressure detecting unit 130 detects applied pressure, and the user provides button input indicating a rightward direction into the button unit 146. Referring to FIG. 10C, if the user inputs button manipulation in the rightward direction into the proximity sensor unit 142, while applying pressure on the pressure detecting unit 130, the mobile device 100 performs the page-turning function as a corresponding function.

FIGS. 11A to 11E illustrate a page-turning function performed in response to a magnitude of pressure detected at the pressure detecting unit 130 and proximate gesture detected at the proximity sensor unit 142, according to an embodiment of the present invention.

Referring to FIGS. 11A to 11E, photographs stored in the mobile device 100 may include a first photograph 1110, a second photograph 1120, a third photograph 1130, and a fourth photograph 1140.

FIG. 11A illustrates an example in which slowly turning photographs page-by-page is performed as a corresponding UI function, when the pressure detecting unit 130 detects “weak” pressure and the proximity sensor unit 142 detects a “near” proximate gesture.
